Design Virtualization Infrastructure

Module 8: Design Virtualization Infrastructure

• Virtualization of a test server environment

• Virtualization and migration of legacy applications

• Design and test a virtualized development environment

Overview of Virtual Server Hosting in Windows Server 2008

Microsoft Virtual Server 2005

System Center Virtual Machine Manager

Hyper-V

Evaluate Appropriateness of Virtualization

Criteria Authentication

Processor % Processor Time Candidates using low utilization are good candidates

Network Interface Byte Total/Sec Packets/Sec Assign shared or dedicated NICs to virtual machines.

Memory Pages/Sec Available Bytes Confirm that the host has available resources.

Physical DiskAverage disk/sec Good candidates can

function with the available disk read performance.

Isolation RequirementsApplications that need to be isolated (not

sharing a server with other applications) are good candidates.

Availability Requirements Mission critical, high availability legacy applications are good candidates.

Scalability RequirementsApplications that will be expected to grow are

good candidates, as a guest machine can be allocated more resources dynamically.

Moving Legacy Applications to Virtual Servers

1. Perform disk maintenance and defragmentation

2. Add firewall exception (RemoteAdmin)

3. Run Convert Physical Server Wizard in VMM Manager
